I used this guide (4th Ed.) during a month-long trip to southern Africa. My other options were Newman's and Roberts. I am so happy with my choice as with this guide -that made its home in my daypack- I could confidently identify virtually 100% of the c. 230 species that crossed my path (just one raptor escaped). This guide proved invaluable, the illustrations are accurate, descriptions quite good and the sonograms were essential for identifying the small Cisticolas. This is the guide for the region! (I suggest buying a small photographic book too, like Burger Cillié's, by Sunbird).
